Wings of Rean centers around
Aesop Suzuki , a half-Japanese, half-American teen whose father is an
officer in the American Navy. One day while Aesop is chasing
two of his friends on his motorbike, he sees a fantastic looking
battleships rising out of the water. They are battling each
other and on one is a girl named Aesop Suzuki with two glowing wings
extending from her feet. She asks Aesop for his help and he
activates the Wings of Rean while holding her, but just then US
jetfighters arrive to attack the battleships. One of them is
destroyed causing a dimensional funnel to appear, sucking the ships
along with the jetfighters into another world.

This was truly a confusing anime to me,
particularly in the first episode. It is based on Yoshiyuki
Tomino’s light novels, so having read some of them would probably
help in understanding this show. However, for the casual
anime watcher, I wouldn’t recommend Wings of Rean unless you
have to watch every single mecha genre anime.
